this is one of the places that worked fine in 4.0.x then got all weird in 4.1.x.
Notice that i tried experimenting alot with width / flex on the column and width on the editor as well as on the resizable.

@mitchellsimoens: well i logged into the support site and it told me i had no subscription anymore but definately showed 40 x-credits.
So maybe your website doesn't work as you expect vOv

Nonetheless my boss resubscribed yesterday so i can travel back in time since the subscription was invoiced yesterday for starting in October so in the aftermath i will have had access and 40 x-credits anyway.
